Each component has its own serial number. Master Collection has an additional serial number for Color Finesse. If you purchased an upgrade, use a qualifying serial number to complete the installation.
Note: When u-boot is partially damaged (but still no output on serial console) it is required to pull CS pin of the SPI flash to GND, in order to enter JTAG mode. When u-boot is completely erased, or damaged from the first sector in flash then CS pin remains low on bootstrap (after initial transition from high to low) and it is not required to short GND pin to CS for JTAG to work.
PowerISO 5 6 Serial
The normal thing is to hook up the serial interface and do some extra commands so the file isn't rejected. A simpler thing is to modify the binary you're using, to match the expected id info above. The stored information in NVRAM is corrupted above..it is all F's. Another possible corruption is all 0's. I used a hex editor (like Flexhex in Windows) and modified locations 0x40 thru 0x47, (which had the 0xc7000002, at least for a OpenWrt binary) and also 0x48 thru 0x4f. I modified those locations to also be all F. (total of 16 bytes of F).
